Nonminimal coupling, equivalence principle and exact Foldy-Wouthuysen transformation

A. Accioly, H. Blas, H. Mukai

It is shown that the exact Foldy-Wouthuysen transformation for spin-0 particles on spacetimes described by the metrics $d{s}^2=V^{2}d{t}^2-W^{2}d{\mathbf{x}}^2$, where $V=V(\mathbf{x})$ a…
